If you have a Cobb AP or similar EM, you don't need either because you can simply disable the code from triggering a CEL.

If you don't, you either need to put the resistor in or yes, you can re-use the sensor in an aftermarket up pipe but that's really not recommended. It can break off and destroy your turbo just like the cat you're replacing (which is the whole point of the mod).

yes, you can do that White GDA, you also now have an EGT sensor dangerously exposed in a way it was not designed to be and in many cases, they break off and blow your turbo. Much like the cat you just replaced...

In other words, the entire purpose of the mod is for turbo safety and putting the damn sensor back in there makes the whole thing kind of moot.

i have a magnaflow catback it is a littile to quiet for me and i dont have the money to buy a downpipe so i was hoping that the up pipe might help a little. ups is having trouble finding my house i have been waiting sience the 12th for my uppipe i see them drive by my house every day how hard is it fedex found it yesterday for my boost controller it ended up being broke so i had to send it back

Also, it will trigger a CEL when it gets hot.

Well I disconnected the EGT sensor and did a resistor mod. I only used the prope to plug the bung in the uppipe. Yep I should have gotten a bolt I guess...but it was too dran hard to find.

I think my EGT sensor was grenaded anyways....as it looked like tiny stubby piece of metal. LOL. Could it really cause all that harm? Out of curiosity....this ever happened to anyone before?

IF it does cause damage then...well...I got an excuse to get a bigger turbo.
